BACKGROUND Background Information

When undertaking projects, such as, for example, woodworking or metalworking projects, a worker may be required to perform repeatableoperations on multiple workpieces. For example, a project may require aworker to crosscut multiple workpieces to the same length. As performingrepeatable operations on multiple workpieces is typically difficult andtime consuming, workers may look for tools to aid the process. However,conventional tools available to workers performing repeatable operationshave some drawbacks including, among others, being inaccurate,inconsistent, and inefficient.

The hex portion 152 may beaccessible through the top opening 144 a of the bore 144, and the footportion 156 may be accessible through the bottom opening 144 b of thebore 144.

As will be described in greater detail below, the locking assembly 104may be utilized to lock the first portion 102 of the first stop assembly56 a in various locations of the third track 76 of the first fence 54 a.Although the locking assembly 104 has been described as including thelocking foot 148 and the nut 150, it is to be understood that othercomponents may be utilized to effect the same result. For example, thelocking assembly 104 may include an engagement member, such as, forexample, a threaded bolt, configured to releasably secure the firstportion 102 with another object, such as, for example, a portion ofanother tool.

The second portion 106 may be substantially identical to the firstportion 102 with several exceptions which will be further describedherein. As such, similar parts are labeled with similar referencenumerals and different parts are labeled with different referencenumerals.

More particularly, and with primary reference to FIG. 4 through FIG. 5and FIG. 7 , a first end surface 158 (FIG. 7 ) of the second portion 106is different than the first end surface 112 of the first portion 102, asecond end surface 160 (FIG. 7 ) of the second portion 106 is differentthan the second end surface 114 of the first portion 102, a top surface162 (FIG. 4 ) of the stem portion 118 of the second portion 106 isdifferent than the top surface 138 of the stem portion 118 of the firstportion 102, a vertically extending bore 164 (FIG. 5 ) defined by thesecond portion 106 is different than the vertically extending bore 144defined by the first portion 102, a longitudinally extending generallycylindrical bore 166 (FIG. 5 ) and a longitudinally extending cavity 168(FIG. 5 ) defined by the second portion 106 is different than thelongitudinally extending bore 146 defined by the first portion 102, anda pivot mount 170 (FIG. 5 ) is added to the second portion 106, whichextends longitudinally away from the second end surface 160 as furtherdescribed below.

With continued reference to FIG. 4 through FIG. 5 and FIG. 7 , thevertically extending bore 164 defined by the second portion 106 mayextend through the top surface 162 of the stem portion 118 of the secondportion 106 and a bottom surface 136 a (FIG. 5 ) of the base portion 116of the second portion 106, which differs from the bottom surface 136 ofthe base portion 116 of the first portion 102 in the size and locationof the bore 164 compared to the bore 144 of the first portion 102. Thebore 164 may be provided generally centrally relative to the top surface162 of the stem portion 118 of the second portion 106, and may have avarying diameter. However, it is to be understood that the bore 164 mayhave any suitable diameter (or diameters), and may be provided in anysuitable location. More particularly, the bore 164 may include a topopening 164 a, a bottom opening 164 b, a first bore section 164 c and asecond bore section 164 d where a diameter of the first bore section 164c tapers downwardly from the top surface 162 and where a diameter of thesecond bore section 164 d is equal to a diameter of an edge 164 e of thefirst bore section 164 c.

The longitudinally extending generally cylindrical bore 166 may extendthrough the first end surface 158 and through the second bore section164 d into the bore 164. The bore 166 may include a first opening 166 aand a second opening 166 b. The first opening 166 a of the bore 166 maybe provided proximate the first end surface 158, and the second opening166 b of the bore 166 may be provided proximate the second bore section164 d of the bore 164.

The cavity 168 may extend through the second bore section 164 d, throughthe second end surface 160 of the second portion 106, and through atleast a part of the pivot mount 170. The cavity 168 may include anopening 168 a and an end 168 b. As such, the opening 168 a of the cavity168 may lead to the bore 164 and the end 168 b of the cavity 168 may beprovided within at least a part of the pivot mount 170. As shown in FIG.5 , the opening 168 a of the cavity 168 may be longitudinally alignedwith the first opening 166 a of the bore 166, the second opening 166 bof the bore 166, the first opening 146 a of the bore 146 and the secondopening 146 b of the bore 146.

The top surface172 may include a first section 172 a and a second section 172 b. Thefirst section 172 a may be coplanar with the top surface 162 of the stemportion 118 of the second portion 106 and may extend longitudinally awayfrom the second end surface 160 of the second portion 106 toward thesecond section 172 b of the top surface 172. The second section 172 bmay extend between the first section 172 a and the bottom surface 174,and, as such, the second section 172 b may have an arcuate portion and astraight portion (i.e., the arcuate portion is between the first section172 a and the straight portion, and the straight portion is between thearcuate portion and the bottom surface 174). The bottom surface 174 maydefine a cavity 176 having an opening 176 a that faces verticallydownward and leads to an interior cavity surface 176 b. As shown in FIG.5 , the cavity 176 may be substantially U-shaped, however, the cavity176 may take on any suitable shape. The first section 172 a of the topsurface 172 may have a width W9. In some implementations, width W9 maybe sized to accommodate at least a portion of the stop portion 110 asmore fully described below, however, width W9 may take on any suitabledimension.

With primary reference to FIG. 4 through FIG. 7 , the fine-adjustmentassembly 108 may include a set screw 178 (FIG. 5 ), an expansion bolt180 (FIG. 5 ), and an adjustment wheel 182 (FIG. 4 ). The set screw 178may include a first end 178 a, a second end 178 b, and a threadedportion 178 c. The expansion bolt 180 may be a female threaded bolt andmay include a first end 180 a and a second end 180 b. The adjustmentwheel 182 may include a first end 182 a, a second end 182 b, an outergenerally cylindrical sidewall 184, and an inner generally cylindricalsidewall 186 (FIG. 5 ). The inner sidewall 186 may define a threadedbore 188 extending longitudinally through the first end 182 a and thesecond end 182 b of the adjustment wheel 182. The threaded bore 188 maydefine a thread axis X4, and the adjustment wheel 182 may rotate aboutthe thread axis X4 as more fully described below.

With primary reference to FIG. 5 , the set screw 178 may be providedwithin the first portion 102 and within the second portion 106. Moreparticularly, the first end 178 a of the set screw 178, which may be acup point end in one implementation, may contact at least a part of thepivot mount 170 at the end 168 b of the cavity 168. The threaded portion178 c of the set screw 178 may extend from the first end 178 a of theset screw 178 longitudinally away from the pivot mount 170 along thecavity 168, out of the opening 168 a of the cavity 168, through a partof the bore 164, threadingly through the threaded bore 188 of theadjustment wheel 182, through a part of the bore 164, through the secondopening 166 b and the first opening 166 a of the bore 166, through thesecond opening 146 b of the bore 146, threadingly through the expansionbolt 180, and through the first opening 146 a of the bore 146 to contactat least a part of the nut 150.

As such, the adjustment wheel 182 may be provided within the bore 164and may be rotatable about the thread axis X4. More particularly, theadjustment wheel 182 rotates about the threaded portion 178 c of the setscrew 178 about the thread axis X4. The fine-adjustment assembly 108 mayfurther include an anti-backlash mechanism 182 c, such as a springmolded within the second portion 106 proximate the first end 182 a ofthe adjustment wheel 182, to reduce and/or prevent backlash associatedwith the linear movement of the second portion 106 and the stop portion110. In some implementations, the fine-adjustment assembly 108 may beused to make adjustments of thousandths of an inch to the location ofthe second portion 106, the stop portion 110, and the stop surface 206of the stop portion 110, however, the range of adjustment of thefine-adjustment assembly 108 may be any suitable range of adjustment.

Although the fine-adjustment assembly 108 has been described asincluding the set screw 178, the expansion bolt 180, and the adjustmentwheel 182, it is to be understood that other components may be utilizedto effect the same result. For example, the first portion 102 may beengaged with the second portion 106 with a link member, such as anelongate rod, and the second portion 106 may include an adjustmentmember, such as, for example, a grip member configured to be gripped byan operator to slidably move the second portion 106 along the elongaterod to make adjustments to components of the first stop assembly 56 a.

With primary reference to FIG. 4 through FIG. 7 , the stop portion 110may include a first pivot portion 190, a second pivot portion 192, apivot shaft 194 (FIG. 5 ), a first end surface 196 (FIG. 6 ), a secondend surface 198, a first side surface 200, a second side surface 202, atop surface 204, and a stop surface 206.

With continued reference to FIG. 4 through FIG. 7 , the first pivotportion 190 may include a pivot surface 208 and an inner side surface210. The second pivot portion 192 may include a pivot surface 212 and aninner side surface 214. The inner side surface 210 of the first pivotportion 190 and the inner side surface 214 of the second pivot portion192 may be transversely spaced from one another and may extendlongitudinally away from the first end surface 196 of the stop portion110.

The pivot shaft 194 may extend in a transverse direction and may beengaged with the inner side surface 210 of the first pivot portion 190on one end and the inner side surface 214 of the second pivot portion192 on the other end at a longitudinal distance away from the first endsurface 196. A void 216 may be defined by a portion of the inner sidesurface 210 of the first pivot portion 190, a portion of the first endsurface 196, a portion of the inner side surface 214 of the second pivotportion 192, and a portion of the pivot shaft 194. The pivot shaft 194may define a pivot axis X5 (FIG. 6 ) defined by the pivot shaft 194.More particularly, the stop portion 110 may be pivotable about the pivotaxis X5 between an engaged position “EP” (FIG. 4 ) and a disengagedposition “DP” (FIG. 6 ) as will be more fully described below.

It should be noted that the pivot surface 208 of the first pivot portion190 and the pivot surface 212 of the second pivot portion 192 may besubstantially identical, and, therefore, only the pivot surface 208 ofthe first pivot portion 190 will be further described herein, and anysuch descriptions applied to the pivot surface 208 of the first pivotportion 190 may be applied to the pivot surface 212 of the second pivotportion 192 as necessary.

With primary reference to FIG. 4 and FIG. 6 through FIG. 7 , the pivotsurface 208 of the first pivot portion 190 may be bounded by a part ofthe inner side surface 210 of the first pivot portion 190, a part of thefirst side surface 200, a part of the top surface 204, and a part of thestop surface 206. Stated otherwise, the pivot surface 208 of the firstpivot portion 190 may extend away from a part of the top surface 204 ina generally arcuate manner between a part of the inner side surface 210of the first pivot portion 190 and a part of the first side surface 200until meeting a part of the stop surface 206.

With primary reference to FIG. 7 , the pivot surface 208 may include afirst section 218, a second section 220, a third section 222, and afourth section 224. More particularly, the first section 218 may be agenerally flat surface provided proximate the top surface 204. When thefirst stop assembly 56 a is viewed from the first side 98 (e.g., similarto the view in FIG. 6 ), the first section 218 may be generally coplanarwith, or slightly vertically above, the top surface 162 of the stemportion 118 of the second portion 106 and vertically above the topsurface 204 of the stop portion 110. Although vertical heights of thefirst section 218, the top surface 162 of the stem portion 118 of thesecond portion 106, and the top surface 204 of the stop portion 110 havebeen described relative to one another, the first section 218, the topsurface 162 of the stem portion 118 of the second portion 106, and thetop surface 204 of the stop portion 110 may take on any suitableheights.

The second section 220 may be a generally arcuate surface (such as, forexample, a cam surface having convex and/or concave portions) extendingbetween the first section 218 and the third section 222. The thirdsection 222 may be a generally flat surface extending between the secondsection 220 and the fourth section 224. The fourth section 224 may be agenerally arcuate surface (such as, for example, a cam surface havingconvex and/or concave portions) extending between the third section 222and a part of the stop surface 206. The configuration of the firstsection 218, the second section 220, the third section 222, and thefourth section 224 may aid the movement of the stop portion 110 into andout of the engaged position EP and the disengaged position DP.

More particularly, when the stop portion 110 is in the disengagedposition DP, the third section 222 (i.e., the generally flat surface)may be engaged with the second end surface 160 of the second portion106. The stop portion 110 may pivot (about the pivot axis X5) in arotational direction toward the first portion 102 when moving from thedisengaged position DP to the engaged position EP. As this occurs, thesecond section 220 (i.e., the cam surface) cammingly engages the secondend surface 160 of the second portion 106 to aid the rotation of thestop portion 110 until the first section 218 (i.e., the generally flatsurface) engages the second end surface 160 of the second portion 106.

Further, when the stop portion 110 is in the engaged position EP, thefirst section 218 (i.e., the generally flat surface) may be engaged withthe second end surface 160 of the second portion 106. The stop portion110 may pivot (about the pivot axis X5) in a rotational direction awaythe first portion 102 when moving from the engaged position EP to thedisengaged position DP. As this occurs, the second section 220 (i.e.,the cam surface) cammingly engages the second end surface 160 of thesecond portion 106 to aid the rotation of the stop portion 110 until thethird section 222 (i.e., the generally flat surface) engages the secondend surface 160 of the second portion 106.

With continued reference to FIG. 4 through FIG. 7 , the first sidesurface 200 may face transversely outward (i.e., away from thelongitudinal axis X2) and may be bounded by a part of the second endsurface 198, a part of the top surface 204, a part of the stop surface206, and a part of the pivot surface 208 proximate the first side 98 ofthe first stop assembly 56 a.

The second side surface 202 may face transversely outward (i.e., awayfrom the longitudinal axis X2) and may be bounded by a part of thesecond end surface 198, a part of the top surface 204, a part of thestop surface 206, and a part of the pivot surface 212 proximate thesecond side 100 of the first stop assembly 56 a.

Further, the second side surface 202 may be spaced a transverse distanceaway from the first side surface 200 that is that is equal to width W8.Stated otherwise, the stop portion 110 may have a width (not shown) thatis equal to (or less than) width W8, which allows at least a part of thestop portion 110 to pass through the front opening 86 of the third track76.

The second end surface 198 may be bounded by a part of the top surface204, a part of the stop surface 206, a part of the first side surface200, and a part of the second side surface 202. The second end surface198 may be an angled surface extending upwardly from the stop surface206 at an acute angle relative to the stop surface.

With primary reference to FIG. 4 , the top surface 204 may include aperimeter region 226 and a recessed region 228. The recessed region 228may include a sidewall 228 a and a bottom surface 228 b. The sidewall228 a may extend away from the perimeter region 226 toward the bottomsurface 228 b. The first pivot portion 190 and the second pivot portion192 may be engaged with a portion of the perimeter region 226.

The stop surface 206 may be a generally flat surface, and may be boundedby a part of the first pivot portion 190, a part of the second pivotportion 192, a part of the first end surface 196, a part of the secondend surface 198, a part of the first side surface 200, and a part of thesecond side surface 202.

In some implementations, the stop surface 206 may have a length (notshown) defined between the first end surface 196 and the second endsurface 198 and a width (not shown) defined between the first sidesurface 200 and the second side surface 202. The width of the stopsurface 206 may be equal to (or less than) width W8, which allows atleast a part of the stop surface 206 to pass through the front opening86 of the third track 76. In some implementations, the stop surface 206may be square in shape (i.e., the length and width of the stop surface206 may be equal), however, it is to be understood that the stop surface206 may take on any suitable dimensions.

As stated above, and as illustrated in FIG. 1 through FIG. 3 , thesystem 10 may utilize four fences (i.e., the first fence 54 a, thesecond fence 54 b, the third fence 54 c, and the fourth fence 54 d),where the first fence 54 a, and the second fence 54 b are engaged withthe top surface 20 of the first table portion 14, and where the thirdfence 54 c and the fourth fence 54 d are engaged with the top surface 28of the third table portion 18 in a substantially identical manner. Assuch, only the engagement of the first fence 54 a and the second fence54 b with the top surface 20 of the first table portion 14 will bedescribed herein. However, any such descriptions may be applied to theengagement of the third fence 54 c and the fourth fence 54 d with thetop surface 28 of the third table portion 18 as necessary.

With primary reference to FIG. 3 and FIG. 10 through FIG. 11 , each ofthe plurality of mounting brackets 58 may be L-shaped members includinga first mount portion 230 and a second mount portion 232. A plurality ofbores 234 (FIG. 11 ) may be defined in the first mount portion 230 (FIG.3 ) and the second mount portion 232 (FIG,3) of each of the plurality ofmounting brackets 58. In some implementations, a plurality of fasteners236 may extend through the plurality of bores 234 to releasably engagethe first fence 54 a with the second fence 54 b and the top surface 20of the first table portion 14 as more fully described below.

With continued reference to FIG. 3 and FIG. 10 through FIG. 11 , thesecond fence 54 b may be provided within the groove 34 such that the topend 60 is positioned proximate the first sidewall 34 a of the groove 34,the second side 70 is positioned proximate the bottom surface 34 c ofthe groove 34, and the bottom end 62 is positioned proximate the secondsidewall 34 b of the groove. The first fence 54 a may be provided suchthat the bottom end 62 of the first fence 54 a releasably engages therecessed region 68 a of the first side 68 of the second fence 54 b.

With continued reference to FIG. 3 and FIG. 10 through FIG. 11 , theplurality of mounting brackets 58 may be aligned with the first fence 54a and the second fence 54 b such that one or more of the plurality ofbores 234 defined in the first mount portion 230 is aligned with thefront opening 82 of the second track 74 of the first fence 54 a and oneor more of the plurality of bores 234 defined in the second mountportion 232 is aligned with the front opening 78 of the first track 72of the second fence 54 b.

One or more fasteners 236 may extend through one or more of theplurality of bores 234 such that a portion of the one or more fasteners236 engages at least the interior surface 84 of the second track 74 ofthe first fence 54 a, the interior surface 80 of the first track 72 ofthe second fence 54 b, and the top surface 20 of the first table portion14 thereby releasably engaging the first fence 54 a and the second fence54 b with one another, and further releasably engaging the first fence54 a and the second fence 54 b to the top surface 20 of the first tableportion 14.

Although the system 10 has been described as releasably engaging thefirst fence 54 a and the second fence 54 b with one another, and furtherreleasably engaging the first fence 54 a and the second fence 54 b tothe top surface 20 of the first table portion 14, it is to be understoodthat other configurations are possible. For example, and in someimplementations, the system 10 may utilize a single vertical fencereleasably engaged with the table 12 (e.g., if there is no groove 34,the first fence 54 a may be releasably engaged with the top surface 20of the first table portion 14), or the system may utilize a singlehorizontal fence releasably engaged with the groove 34 of the table 12(e.g., if there is a groove 34, the second fence 54 b may be releasablyengaged with groove 34 in any suitable manner).

It should further be noted that the second end 66 of the first fence 54a and the second end 66 of the second fence 54 b may be positioned toserve as an extension to another fence assembly, such as, for example, amiter saw fence assembly, or, alternatively, positioned proximate acutting blade of a machine tool, such as, for example, a cutting bladeof a miter saw.

Having thus described the structure of the system 10, and its associatedcomponents, primary reference is now made to FIG. 8 through FIG. 15 todepict one exemplary implementation and operation of the system 10. Inthis implementation, the system 10 will be described as utilizing twofences, two stop assemblies, and multiple mounting brackets to measurelengths of workpieces to be cut by the cutting blade 44. As shown inFIG. 8 , a measurement device 11, such as a ruler, may be engaged withthe first fence 54 a to measure a distance from the cutting blade 44.

With primary reference to FIG. 8 , the first stop assembly 56 a may beinserted within the third track 76 of the first fence 54 a. It should benoted that the stop portion 110 of the first stop assembly 56 a may bein either the disengaged position DP or the engaged position EP whenbeing inserted into the first fence 54 a.

As shown in FIG. 8 , the first stop assembly 56 a is in the disengagedposition DP. The first stop assembly 56 a may be inserted within thethird track 76 such that the stop surface (not shown in FIG. 8 ) of thestop portion 110 faces the interior surface 88 of the third track 76 andthe second end 96 of the first stop assembly 56 a is the first part ofthe first stop assembly 56 a to enter the third track 76. It should benoted that in some implementations, when the first stop assembly 56 a isin the disengaged position DP, the entirety of the first stop assembly56 a may be positioned within the track and coplanar with, or inwardlyof, the imaginary longitudinal vertical plane P. This is beneficial asno portion of the first stop assembly 56 a extends into a working areaproximate the first fence 54 a.

As the first stop assembly 56 a is inserted into the third track 76, thefirst top surface 132 of the base portion 116 of the first portion 102and the second portion 106, and the second top surface 134 of the baseportion 116 of the first portion 102 and the second portion 106 slidablyengage the interior surface 88 of the third track 76 (i.e., an area ofthe base portion 88 a of the interior surface 88 is engaged). As shownin FIG. 8 , the stop portion 110 may be accessible through the frontopening 86 of the third track 76.

With primary reference to FIG. 8 and FIG. 9 , the first stop assembly 56a may be slidably moved in a direction generally indicated at arrow “A”to a desired location along the third track 76, which, in thisimplementation, is a location proximate to where the stop surface 206 ofthe stop portion 110 needs to be when the stop portion 110 is in theengaged position EP (i.e., the 45-inch mark on the measurement device

Once the first stop assembly 56 a is moved to a location near thedesired location, the hex portion 152 may be rotated which, in turn,rotates the threaded portion 154, which, in turn, moves the foot portion156 in a transverse direction until the foot portion 156 engages theinterior surface 88 of the third track 76. This causes the first topsurface 132 of the base portion 116 of the first portion 102 and thesecond portion 106, and the second top surface 134 of the base portion116 of the first portion 102 and the second portion 106 to engage theinterior surface 88 of the third track 76 with sufficient force to lockthe first portion 102 of the first stop assembly 56 a in that location.

With primary reference to FIG. 11 , the first stop assembly 56 a may bemoved from its disengaged position DP to its engaged position EP bypivoting the stop portion 110 (in a direction generally indicated atarrow “B”) through the front opening 86 of the third track 76 until thestop portion 110 is substantially perpendicular, or perpendicular, to atleast the first portion 102, the second portion 106, or the frontopening 86 of the third track 76. Although the stop surface 206 of thestop portion 110 is shown as being a flat surface, it is to beunderstood that the stop surface may take on any suitable shape and/orconfiguration. In some implementations, the stop portion 110 may pivotabout the pivot axis X5 90 degrees or less between the disengagedposition DP and the engaged position EP. However, it is to be understoodthat the stop portion 110 may have any suitable range of rotation.

Now that the movement of the first stop assembly 56 a relative to thefirst fence 54 a has been described, an implementation showing the firststop assembly 56 a and the second stop assembly 56 b engaged with thefirst fence 54 a will be described. With primary reference to FIG. 12through FIG. 15 , the first stop assembly 56 a and the second stopassembly 56 b are located at a position near a desired location of thestop surface 206 of the stop portion 110. More particularly, and in thisimplementation, the first stop assembly 56 a is not at the desiredlocation (i.e., the desired location of the stop surface 206 of the stopportion 110 is the 42-inch mark on the measurement device 11 as shown inFIG. 13 ), and second stop assembly 56 b is not at the desired location(i.e., the desired location of the stop surface 206 of the stop portion110 is the 47-inch mark on the measurement device 11 as shown in FIG. 15). As the first stop assembly 56 a is not at the desired location, thefine-adjustment assembly 108 may be utilized to move the first stopassembly 56 a to the desired location as more fully explained below.

With primary reference to FIG. 12 through FIG. 15 , and in someimplementations, the stop portion 110 may be pivoted from the disengagedposition DP to the engaged position EP, and, when this occurs, the stopsurface 206 of the stop portion 110 may be at a distance greater thanthe desired location (e.g., the 42-inch mark and the 47-inch mark). Inorder for the stop surface 206 of the stop portion 110 of the first stopassembly 56 a to be positioned at the 42-inch mark, and in order for thestop surface 206 of the stop portion 110 of the second stop assembly 56b to be positioned at the 47-inch mark, the stop portion 110 needs tomove in a linear direction (e.g., a longitudinal direction) as morefully described herein.

To accomplish this, the adjustment wheel 182 may be rotated in adirection generally indicated at arrow “C” which, in turn, causes thesecond portion 106 and the stop portion 110 to move in a lineardirection (e.g., a longitudinal direction) generally indicated at arrow“D” away from the first portion 102.

More particularly, the adjustment wheel 182 may rotate about the threadaxis X4 which, in turn, causes the adjustment wheel 182 to engage thesecond bore section 164 d of the bore 164 and provide a linear force tomove the second portion 106 and the stop portion 110 away from the firstportion 102 in the linear direction (e.g., the longitudinal direction)until the stop surface 206 of the stop portion 110 of the first stopassembly 56 a is precisely aligned with the 42-inch mark of themeasurement device 11 (e.g., the stop surface 206 is perpendicular tothe front opening 86 of the third track 76 at the 42-inch mark (FIG. 13)), and the stop surface 206 of the stop portion 110 of the second stopassembly 56 b is precisely aligned with the 47-inch mark of themeasurement device 11 (e.g., the stop surface 206 is perpendicular tothe front opening 86 of the third track 76 at the 47-inch mark (FIG. 14).

Generally, once the stop surface 206 of the stop portion 110 is at thedesired location, the stop surface 206 may releasably engage aworkpiece. For example, the workpiece may be a piece of wood having alength greater than a required cut length (e.g., the workpiece may havea length of 60 inches and needs to be crosscut to a length of 47 inches,or a length of 60 inches and needs to be crosscut to a length of 42inches). As such, a side of the workpiece may releasably engage thefirst side 68 of the first fence 54 a and an end of the workpiece mayreleasably engage the stop surface 206 of the stop portion 110 as morefully described below.

For example, the workpiece may slidably move along the first side 68 ofthe first fence 54 a until an end of the workpiece engages the stopsurface 206 of the stop portion 110. The end of the workpiece may remainengaged with the stop surface 206 until a crosscut operation isperformed on the workpiece, which results in the workpiece having anecessary length.

This process may be repeated to crosscut other workpieces to the samelength with accuracy, consistency, and efficiency, or to any otherdesired length with accuracy, consistency, and efficiency by relocatingthe stop surface 206 of the stop portion 110 to another desiredlocation.

With primary reference to FIG. 14 and FIG. 15 , an implementationshowing a first workpiece 13 engaging the stop surface 206 of the stopportion 110 of the second stop assembly 56 b at a first measured length(i.e., a cut length of the first workpiece 13 relative to the cuttingblade 44) and a second workpiece 15 engaging the stop surface 206 of thestop portion 110 of the first stop assembly 56 a at a second measuredlength (i.e., a cut length of the second workpiece 15 relative to thecutting blade 44).

With primary reference to FIG. 14 , the stop surface 206 of the stopportion 110 of the second stop assembly 56 b is located at a firstdesired location (i.e., a cut length of the first workpiece 13 relativeto the cutting blade 44). The second stop assembly 56 b is in theengaged position EP and an end 13 a of the first workpiece 13 is engagedwith the stop surface 206 of the stop portion 110 of the second stopassembly 56 b. The end 13 a of the first workpiece 13 may remain engagedwith the stop surface 206 of the stop portion 110 until a crosscutoperation is performed on the first workpiece 13. The second stopassembly 56 b may remain in that location in order to cut additionalworkpieces to that same length. Alternatively, the second stop assembly56 b may be moved to another desired location to cut workpieces to adifferent length.

With primary reference to FIG. 15 , the first stop assembly 56 a islocated at a second desired location (i.e., a cut length of the secondworkpiece 15 relative to the cutting blade 44, which is different thanthe cut length of the first workpiece 13 shown in FIG. 14 ). The firststop assembly 56 a is in the engaged position EP and an end 15 a of thesecond workpiece 15 is engaged with the stop surface 206 of the stopportion 110 of the first stop assembly 56 a. The end 15 a of the secondworkpiece 15 may remain engaged with the stop surface 206 of the stopportion 110 until a crosscut operation is performed on the secondworkpiece 15. The first stop assembly 56 a may remain in that locationin order to cut additional workpieces to that same length.Alternatively, the first stop assembly 56 a may be moved to anotherdesired location to cut workpieces to a different length.

One of the benefits of using more than one stop assembly includes beingable to perform multiple repeatable operations with varying parameterson multiple workpieces (e.g., workpieces need to be crosscut todifferent lengths with a miter saw). For example, if more than one stopassembly is utilized, a first stop assembly may be positioned at a firstdesired location (associated with a first workpiece cut length) and asecond stop assembly may be positioned at a second desired location(associated with a second workpiece cut length).

When a workpiece needs to be cut to the first workpiece cut length, thefirst stop assembly may be pivoted to the engaged position, and, if thesecond stop assembly is at a closer position to the machine tool thanthe first stop assembly, the second stop assembly may be pivoted to thedisengaged position (positioning the entire stop assembly coplanar with,or inwardly of, the imaginary longitudinal vertical plane) to allow theworkpiece to pass by the second stop assembly and engage the first stopassembly. Likewise, when a workpiece needs to be cut to the secondworkpiece cut length, the second stop assembly may be pivoted to theengaged position, and, if the first stop assembly is at a closerposition to the machine tool than the second stop assembly, the firststop assembly may be pivoted to the disengaged position (positioning theentire stop assembly coplanar with, or inwardly of, the imaginarylongitudinal vertical plane) to allow the workpiece to pass by the firststop assembly and engage the second stop assembly.

It should be noted that structures disclosed as being separately formedcan, in other examples, be integrally formed and vice versa. Forexample, while the pivot shaft 194 has been described as being anelement of the stop portion 110 of the first stop assembly 56 a, it isto be understood that the pivot shaft 194 may be a separate elementoperably engaged with the second portion 106 and the stop portion 110,or with any suitable element of the first stop assembly 56 a.

Various inventive concepts may be embodied as one or more methods, ofwhich an example has been provided. The acts performed as part of themethod may be ordered in any suitable way. Accordingly, embodiments maybe constructed in which acts are performed in an order different thanillustrated, which may include performing some acts simultaneously, eventhough shown as sequential acts in illustrative embodiments.

While various inventive embodiments have been described and illustratedherein, those of ordinary skill in the art will readily envision avariety of other means and/or structures for performing the functionand/or obtaining the results and/or one or more of the advantagesdescribed herein, and each of such variations and/or modifications isdeemed to be within the scope of the inventive embodiments describedherein. More generally, those skilled in the art will readily appreciatethat all parameters, dimensions, materials, and configurations describedherein are meant to be exemplary and that the actual parameters,dimensions, materials, and/or configurations will depend upon thespecific application or applications for which the inventive teachingsis/are used. Those skilled in the art will recognize, or be able toascertain using no more than routine experimentation, many equivalentsto the specific inventive embodiments described herein. It is,therefore, to be understood that the foregoing embodiments are presentedby way of example only and that, within the scope of the appended claimsand equivalents thereto, inventive embodiments may be practicedotherwise than as specifically described and claimed. Inventiveembodiments of the present disclosure are directed to each individualfeature, system, article, material, kit, and/or method described herein.In addition, any combination of two or more such features, systems,articles, materials, kits, and/or methods, if such features, systems,articles, materials, kits, and/or methods are not mutually inconsistent,is included within the inventive scope of the present disclosure.

All definitions, as defined and used herein, should be understood tocontrol over dictionary definitions, definitions in documentsincorporated by reference, and/or ordinary meanings of the definedterms.

The articles “a” and “an,” as used herein in the specification and inthe claims, unless clearly indicated to the contrary, should beunderstood to mean “at least one.” The phrase “and/or,” as used hereinin the specification and in the claims (if at all), should be understoodto mean “either or both” of the elements so conjoined, i.e., elementsthat are conjunctively present in some cases and disjunctively presentin other cases. Multiple elements listed with “and/or” should beconstrued in the same fashion, i.e., “one or more” of the elements soconjoined. Other elements may optionally be present other than theelements specifically identified by the “and/or” clause, whether relatedor unrelated to those elements specifically identified. Thus, as anon-limiting example, a reference to “A and/or B”, when used inconjunction with open-ended language such as “comprising” can refer, inone embodiment, to A only (optionally including elements other than B);in another embodiment, to B only (optionally including elements otherthan A); in yet another embodiment, to both A and B (optionallyincluding other elements); etc. As used herein in the specification andin the claims, “or” should be understood to have the same meaning as“and/or” as defined above. For example, when separating items in a list,“or” or “and/or” shall be interpreted as being inclusive, i.e., theinclusion of at least one, but also including more than one, of a numberor list of elements, and, optionally, additional unlisted items. Onlyterms clearly indicated to the contrary, such as “only one of” or“exactly one of,” or, when used in the claims, “consisting of,” willrefer to the inclusion of exactly one element of a number or list ofelements. In general, the term “or” as used herein shall only beinterpreted as indicating exclusive alternatives (i.e. “one or the otherbut not both”) when preceded by terms of exclusivity, such as “either,”“one of,” “only one of,” or “exactly one of.” “Consisting essentiallyof,” when used in the claims, shall have its ordinary meaning as used inthe field of patent law.

As used herein in the specification and in the claims, the phrase “atleast one,” in reference to a list of one or more elements, should beunderstood to mean at least one element selected from any one or more ofthe elements in the list of elements, but not necessarily including atleast one of each and every element specifically listed within the listof elements and not excluding any combinations of elements in the listof elements. This definition also allows that elements may optionally bepresent other than the elements specifically identified within the listof elements to which the phrase “at least one” refers, whether relatedor unrelated to those elements specifically identified. Thus, as anon-limiting example, “at least one of A and B” (or, equivalently, “atleast one of A or B,” or, equivalently “at least one of A and/or B”) canrefer, in one embodiment, to at least one, optionally including morethan one, A, with no B present (and optionally including elements otherthan B); in another embodiment, to at least one, optionally includingmore than one, B, with no A present (and optionally including elementsother than A); in yet another embodiment, to at least one, optionallyincluding more than one, A, and at least one, optionally including morethan one, B (and optionally including other elements); etc.

When a feature or element is herein referred to as being “on” anotherfeature or element, it can be directly on the other feature or elementor intervening features and/or elements may also be present. Incontrast, when a feature or element is referred to as being “directlyon” another feature or element, there are no intervening features orelements present. It will also be understood that, when a feature orelement is referred to as being “connected”, “attached” or “coupled” toanother feature or element, it can be directly connected, attached orcoupled to the other feature or element or intervening features orelements may be present. In contrast, when a feature or element isreferred to as being “directly connected”, “directly attached” or“directly coupled” to another feature or element, there are nointervening features or elements present. Although described or shownwith respect to one embodiment, the features and elements so describedor shown can apply to other embodiments. It will also be appreciated bythose of skill in the art that references to a structure or feature thatis disposed “adjacent” another feature may have portions that overlap orunderlie the adjacent feature.

Spatially relative terms, such as “under”, “below”, “lower”, “over”,“upper”, “above”, “behind”, “in front of”, and the like, may be usedherein for ease of description to describe one element or feature'srelationship to another element(s) or feature(s) as illustrated in thefigures. It will be understood that the spatially relative terms areintended to encompass different orientations of the device in use oroperation in addition to the orientation depicted in the figures. Forexample, if a device in the figures is inverted, elements described as“under” or “beneath” other elements or features would then be oriented“over” the other elements or features. Thus, the exemplary term “under”can encompass both an orientation of over and under. The device may beotherwise oriented (rotated 90 degrees or at other orientations) and thespatially relative descriptors used herein interpreted accordingly.Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal”,“lateral”, “transverse”, “longitudinal”, and the like are used hereinfor the purpose of explanation only unless specifically indicatedotherwise.

Although the terms “first” and “second” may be used herein to describevarious features/elements, these features/elements should not be limitedby these terms, unless the context indicates otherwise. These terms maybe used to distinguish one feature/element from another feature/element.Thus, a first feature/element discussed herein could be termed a secondfeature/element, and similarly, a second feature/element discussedherein could be termed a first feature/element without departing fromthe teachings of the present invention.

An embodiment is an implementation or example of the present disclosure.Reference in the specification to “an embodiment,” “one embodiment,”“some embodiments,” “one particular embodiment,” “an exemplaryembodiment,” or “other embodiments,” or the like, means that aparticular feature, structure, or characteristic described in connectionwith the embodiments is included in at least some embodiments, but notnecessarily all embodiments, of the invention. The various appearances“an embodiment,” “one embodiment,” “some embodiments,” “one particularembodiment,” “an exemplary embodiment,” or “other embodiments,” or thelike, are not necessarily all referring to the same embodiments.

If the specification or claim refers to “a” or “an” element, that doesnot mean there is only one of the element. If the specification orclaims refer to “an additional” element, that does not preclude therebeing more than one of the additional element.

As used herein in the specification and claims, including as used in theexamples and unless otherwise expressly specified, all numbers may beread as if prefaced by the word “about” or “approximately,” even if theterm does not expressly appear. The phrase “about” or “approximately”may be used when describing magnitude and/or position to indicate thatthe value and/or position described is within a reasonable expectedrange of values and/or positions. For example, a numeric value may havea value that is +/−0.1% of the stated value (or range of values), +/−1%of the stated value (or range of values), +/−2% of the stated value (orrange of values), +/−5% of the stated value (or range of values), +/−10%of the stated value (or range of values), etc. Any numerical rangerecited herein is intended to include all sub-ranges subsumed therein.

Additionally, the method of performing the present disclosure may occurin a sequence different than those described herein. Accordingly, nosequence of the method should be read as a limitation unless explicitlystated. It is recognizable that performing some of the steps of themethod in a different order could achieve a similar result.

In the claims, as well as in the specification above, all transitionalphrases such as “comprising,” “including,” “carrying,” “having,”“containing,” “involving,” “holding,” “composed of,” and the like are tobe understood to be open-ended, i.e., to mean including but not limitedto. Only the transitional phrases “consisting of” and “consistingessentially of” shall be closed or semi-closed transitional phrases,respectively.

In the foregoing description, certain terms have been used for brevity,clearness, and understanding. No unnecessary limitations are to beimplied therefrom beyond the requirement of the prior art because suchterms are used for descriptive purposes and are intended to be broadlyconstrued.

Moreover, the description and illustration of various embodiments of thedisclosure are examples and the disclosure is not limited to the exactdetails shown or described.
